Starting from April 1st, 2026, Japan will introduce a new system that imposes monetary penalties on cyclists for a wide range of traffic violations, and this update to the Road Traffic Law will affect not only locals but also tourists who choose to rent bikes or explore Japan on two wheels. If you're planning a cycling trip during your stay—or even just borrowing a mamachari for a casual ride—it's important to understand the rules to avoid unexpected fines.
Under the new system, police will begin issuing "blue tickets" for minor infractions, which means violators will be required to pay fines but will not face criminal charges. Fines will range from 3,000 JPY to 12,000 JPY (about $20 to $85 USD at the time of writing), depending on the severity of the violation.

Some common examples include:
-
12,000 JPY for using a smartphone while riding
-
6,000 JPY for running a red light or riding on the wrong side of the road
-
3,000 JPY for riding side by side or doubling up on one bike
There are 113 violations that can result in a fine. More serious offenses like drunk cycling or tailgating are already penalized under a different system and involve referral to prosecutors.
While the law technically applies to anyone 16 and older, police have indicated they will focus on more dangerous behavior or riders who ignore previous warnings. That means casual mistakes may be met with education rather than immediate fines, but it's best not to count on leniency.
Cycling remains a convenient and scenic way to see Japan, but staying on the correct side of the road, obeying traffic signals, and keeping your phone in your pocket can now save you both trouble and money.
If you’re planning to rent a bike in Japan in or after 2026, consider brushing up on local cycling rules beforehand or asking the rental shop for a quick overview before heading out.
